minor byobu interface change

[Dustin Kirkland]

I don't know that it matters that much, as I don't see many byobu
screenshots in the documentation, but just a heads up on a minor UI
change...

The "logo" as displayed in the bottom left hand corner of byobu has
changed from the three-colored \o/ to a white U on a purple
background.  This minor change brings the new Ubuntu branding to byobu
and the command line.  This is byobu-2.68-0ubuntu1, which is awaiting
approval in the Lucid queue.

Two screenshots which demonstrate the change:

 * After:  http://people.canonical.com/~kirkland/byobu2.png
